LOOKING RING FOR SEPABABLE'BIMS.

Application filed August 8, 1922.

' ments in separable rims for motor vehicles and its particular objectis to provide a locking ring for the rim of the character described. Itis proposed to provide a lockin ring that can be easily secured in placean easily removed. It is further proposed to use a. simple flat ring forthis purpose which engages one side of the felloe and extends beyond'thesame for holding the rim in place. It is further intended to providemeans which will firmly lock the ring so as to prevent the same fromworking loose after it has been secured in place.

The preferred form of my invention is illustrated in the accompanyingdrawing in which Figure 1 represents a side view of a 1 wheel having myring attached thereto, F igure 2 an enlarged detail view showing theparticular construction of my locking means, Figure 3 a cross-sectionalong line 33 of Figure 1, Figure 4 a cross section along line 4-4 ofFigure 2 and Figure 5 a section taken along line V-V of Figure 2,showing the locking means both in an operative and in an inoperativeposition. While I have shown only the preferred form of the invention Iwish to have it understood that various changes or modifications may bemade within the scope of the claim hereto attached without departingfrom the spirit of the invention.

The felly band (2) is provided with one,

radially extending circumferential flange (5) and is permanently securedto the folly in any suitable manner. The tire (4) is held Serial No.580,461.

eral outer face of the flange (18). The felloe is provided with aplurality of transverse bolts (7) terminating at the outside of thefelloe in projections (8) rising from the face of the felloe on anincline as shown in Figure (4). These projections are preferably ofrectangular cross-sections. Thering (6) is provided with a correspondingnumber of slots (9) adapted to engage the slanting proj ections of thefelloe. It will be readily seen that in order to secure the ring to thefelloe I it is necessary to cause the slots to register with theirrespective projections and to slightly turn the ring to complete theengagement. This turning motion is brought, about by means of the cam(11) secured on a pin (12) rotatably supported in the felloe (3). Thecam operates in a" perforation (13) in the ring and when the pin 12) 'isturned to I the right the cam forces the whole ring to the right wherebythe latter due to the engagement of its slots with the slanting provjections of the felloe is pressed tightly against the latter. The pin(12) may be actuated by any suitable means, as for instance, by a monkeywrench engaging its squared end (14).

To look the cam in its final or active position I provide a lock nut(16) which threadedly engages the pin (12) in adjacent relation to thecam (11). This nut is shaped so as to normally not project over theoutlines of the cam (11) and therefore does not interfere with thepressing of the ring on the felloe nor with the turning operation. Afterthe ring has assumed its final position the lock nut may be turned alittle further than the cam by means of a wrench engaging its flat sides(17) and it will then project beyond the outlines .of the cam and engagethe marginal portion of the ring defining the recess (13) with aresulting binding action between the nut and the ring which prevents theformer from working loose and holds the cam in place.

The operation of my device will be readily understood from the foregoingdescription. To secure the ring in place it is only necessary to engagethe slots (9) with the projections (8) and to then turn the pin (12) bymeans of a wrench when the cam (11)-will force the ring in close contactwith the felloe. The operator may then give a slight additional turn tothe lock nut (16) which will engage the margin of the ring and bear onthe same so as to lock the Whole combination. ative to the felloe,comprising a transverse I claim: pin iotatablein the felioe having a camthere- Locking means for an annular element on engaging a slot in thering and a nut 1 separably disposed on a felloe, comprising a threadedlyengaging the pin adapted to bear 5 ring, slanting means associated Withthe gfelion-thenmrgin defining the slot for holding loe adapted toengage the ring and means the cam in its active position for impartingrotary motion to the rin'grel- THOMAS D.
